What is TensorBlock Forge?

For developers building with AI, managing multiple model APIs from providers like OpenAI, Anthropic, and Google is a complex task that slows down development. Forge is an open-source middleware service designed to eliminate this friction. It provides a single, secure, and unified API, allowing you to seamlessly switch between models and providers without rewriting your application code.

Key Features

Forge gives you the tools to build faster and more flexible AI applications by simplifying the infrastructure layer.

🔗 Unify All Your AI Models Connect to dozens of providers—including OpenAI, Anthropic, Google, Mistral, and Cohere—through one consistent API endpoint. This eliminates the need to write and maintain fragile "glue code" for each service, saving you significant development time.
🛡️ Centralize and Secure Your API Keys Store your provider keys once in Forge's secure, encrypted vault. All keys are encrypted at rest using strong Fernet (AES-128) encryption and are only decrypted in memory during a request. Your end applications interact with a single Forge API key, dramatically improving your security posture.
⚙️ Integrate in Minutes with OpenAI Compatibility Forge is engineered as a drop-in replacement for the standard OpenAI API. This means you can integrate it into your existing tools, frameworks, and applications (like LobeChat, CherryStudio, or custom scripts) with minimal to no code changes.
🗺️ Create Custom Model Aliases Simplify your application logic with model mapping. You can create intuitive aliases for complex provider model names (e.g., map "my-fast-model" to claude-3-haiku-20240307). This keeps your code cleaner, more readable, and model-agnostic.

How Forge Solves Your Problems:

Forge is built to address practical, real-world development challenges. Here’s how you can put it to work:

Build a Cost-Optimized, Multi-Model Application Imagine you're building an AI agent that needs a powerful model for complex reasoning but a faster, cheaper model for simple summarization tasks. With Forge, you can route requests to gpt-4o for analysis and claude-3-haiku for summarization through the same API, using custom model aliases to keep your code simple. This allows you to optimize for both performance and cost without architectural overhead.
Secure Internal Tools with a Self-Hosted Gateway Your company is developing an internal code copilot that needs access to several proprietary and open-source models. Instead of embedding sensitive API keys in your internal applications, you can deploy Forge on your own infrastructure. This gives you a single, secure gateway where you retain complete control over keys, access policies, and data flow, ensuring maximum security and compliance.
Accelerate Prototyping and Model Evaluation You need to benchmark five different models to find the best fit for a new feature. Instead of writing five separate integrations, you can use Forge. Simply add each provider's key, and then switch between models by changing a single parameter in your API call. This turns a multi-day task into a matter of minutes, allowing you to focus on model performance, not boilerplate code.

Why Choose Forge?

Truly Open Source and Community-Driven Forge isn't just "source-available"; it's a fully open-source project. This guarantees transparency into its security and functionality. You can fork the code, contribute new features, add provider adapters, and self-host for complete control over your AI stack without vendor lock-in.
Designed for the Modern AI Stack Forge is more than a simple proxy. It's built as foundational infrastructure for an agent-native world. Whether you're orchestrating multi-model chains or building complex agents, Forge provides the robust routing and management layer you need, right out of the box.

Conclusion:

Forge empowers you to build more powerful, flexible, and secure AI applications by abstracting away the complexity of a fragmented ecosystem. By unifying provider APIs and centralizing key management, it lets you focus on creating value, not managing infrastructure.
